Typology and cartography of the south of Tlemcen (western Algeria)

Abstract

The northern area of the Tlemcen mountains was characterized by steppes rich in perennial Poaceae, currently these grasses have disappeared to the detriment of annual Poaceae. This study aims to produce a physiognomic map of the steppe landscape using the most precise, sensitive, and stable indicator, vegetation. The joint use of statistical analysis (CFA) of interspecific linkages was applied to our floristic surveys, which allowed us to sketch the contours of a current physiognomic and typology map of the steppe landscape to appreciate the current state of the natural distribution area of this steppe landscape.
